Security Enhancements
This release introduces the following security enhancements:
•
PXM45—Secure File Transfer (SFTP)
•
RPM-XF—Secure Shell (SSH) for RPM-XF
SFTP and SSH Features
Cisco MGX switches currently support the following remote access applications and protocols:
•
Telnet, FTP, and SSH on the PXM45 controllers
•
Telnet and FTP on the RPM-XF and RPM-PR cards
This release adds SFTP to the PXM45 card and SSH to the RPM-XF card. SFTP is an alternative to FTP
that provides for secure (and authenticated) file transfer between a PXM card and a remote host.
For more information about managing Telnet and SSH features, see the following:

Release Notes for Cisco MGX Route Processor Module (RPM-XF) Cisco IOS Release 12.4(6)T for
PXM45-based Switches, Release 5.3.00
– Secure Shell (SSH) section
Disabling Telnet and FTP
By default, the PXM45 permits unsecured access from Telnet and FTP clients, as well as secure access
from SSH and SFTP clients. A new option (16) of the cnfndparm command, along with an existing
option (15), disables unsecured Telnet and FTP access from remote hosts, while permitting secure SFTP
and SSH sessions.
Option 15
Type yes to disable Telnet access to this switch. Type no to enable Telnet access.
Default: no (Telnet access is enabled)
Option 16
Type yes to disable unsecured access to this switch, either Telnet or FTP. Changing this
option from no to yes automatically changes Option 15 to yes. Changing from yes to
no has no affect on Option 15.
Default: no (Unsecured access is enabled)
If you plan to use SFTP and SSH on the PXM45, you should consider disabling FTP and Telnet access
to improve security. Telnet and FTP transfer all user ID, password, and session management information
between the client and the PXM45 using clear text. Clear, or unencrypted, text can be read by network
analysis and snooping tools.
Initializing SFTP
Upgrading PXM software is not sufficient to initialize and enable the SFTP feature. You must initialize
the sshd_config file and reset the MGX chassis. Because resetting a chassis can interrupt traffic, you
should initialize SFTP before upgrading software so you don’t need to reset it later.
To initialize SFTP, perform the following steps:
Step 1
Initiate an FTP session with the PXM card.
Step 2
Change to the F:/SSHD directory.
Step 3
Get the sshd_conf file from the F:/SSHD directory.
Step 4
Append the line subsystem sftp sftp to the file.
Step 5
Put the sshd_conf file into the F:/SSHD directory.
Step 6
Proceed with the normal software upgrade procedure. Alternatively, enter the resetsys command to reset
the chassis.
Note
The resetsys command interrupts all traffic on the MGX chassis.

Release 5.3.00 Features and Enhancements
Remote IP Management Connection Enhancements
You can manage an MGX 8850 node directly from an Ethernet or console port on the PXM, or you can
configure a remote path to the PXM through a service module or route processor module. The following
management paths are supported in prior releases:
•
AXSM or MPSM to PXM
•
RPM-XF or RPM-PR to PXM
Earlier releases supported intranode connections only, and you could only have one PVC between an
RPM and PXM. Release 5.3.00 enhances the atm0 feature to internode connections, where an RPM on
one MGX switch connects to PXMs on other MGX switches using PNNI. And now you can manage
multiple PXMs from a single RPM.
Management Connection Limitations
The IP addresses of hosts accessing the MGX 8850 node are stored in a RAM cache. Because this cache
has a limit of 50 entries, only 50 IP hosts can actively access the node at one time. New IP hosts are
blocked until the cache clears (as result of inactivity from some hosts) to make room for new entries.
Multiple RPMs can connect to the same PXM, but each RPM can have only one connection to the PXM.
This is because the PXM has a single atm0 address.
Note
If you are connected to the MGX switch using the RPM and accidentally delete the SPVC, the
connection drops. To restore RPM access, you must re-add the SPVC using the console port or Ethernet
port.
Note
The clrallcnf, clrcnf, or clrsmcnf commands clear management connections. To restore RPM access,
you must reconfigure the RPM and PXM cards for IP connectivity using the console port or Ethernet
port.
Configuring an RPM Management Connection
The following quick start procedure summarizes the RPM configuration procedure. This procedure
assumes the RPM already has a switch partition configured for the management connection.
Command
Action
Step 1

Platform Enhancements
This release adds the following MGX platform enhancements.
•
DB Server/Client enhancement
The server automatically copies database tables to the new directory for a release.
•
Software FPGA upgrade on PXM45/C
Cisco uses this feature to upgrade hardware (Field Programmable Gate Array) FPGA images
without introducing new hardware versions. This simplifies the process of adding or changing
features and can reduce hardware costs for both Cisco and customers.
•
PXM to MPSM QoS enhancement
Currently, traffic sent to the MPSM-T3E3-155 and MPSM-16-T1/E1 cards is managed by the class
of service only. For example, the CBR traffic class is always given priority over the VBR.RT traffic
class, even if VBR.RT connections are committed and data received is within the SCR limit.
Through this QoS enhancement, the PXM QE1210 is programmed using information from the
MPSM so it can manage traffic dynamically based on the committed rate of the connections and
interface policy.

Limitations, Restrictions, and Notes for 5.3.00
This section includes information about limitations, restrictions, and notes pertaining to MGX
Release 5.3.00.
•
Due to granularity limitations in the AXSM-E hardware, cell traffic does not reach the configured
peak cell rate (PCR) rate when weighted fair queuing (WFQ) is enabled. You must configure
connections that have WFQ enabled with a PCR of 101 percent of the actual required rate. Available
bit rate (ABR) has the same Qbin priority as the unspecified bit rate (UBR) in the SCT tables. In this
case, ABR and UBR share excess bandwidth if WFQ is enabled.
•
The VXSM cards, when installed for the first time or after clearing the slot configuration, create a
default configuration. The creation of a default configuration involves writing large amount of data
to the hard disk in the node.
When multiple VXSM cards are installed simultaneously or the configuration of multiple VXSM
slots are cleared simultaneously, one or more VXSM cards could fail to be installed. This potential
failure results in following recommendations (refer to CSCed12646):
– Install VXSM cards, using the setrev command, one at a time. Install another VXSM after the
earlier one is completely installed and is Active.
– Clear the VXSM slot configuration using the clrsmcnf command (with no option where the slot
primary software version is preserved) one at a time. Wait until the VXSM rebuilds after
clearing its slot configuration (without clearing the slot primary software version) before
clearing the slot configuration of another VXSM slot.
Upgrading the VISM-PR Image
If you are upgrading the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image
from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E
or PXM45 cards in the same node.

Part Number OL-8892-01 Revision B0, October 23, 2006
15
Limitations, Restrictions, and Notes for 5.3.00
Do not configure the new VISM features until you have fully upgraded the network. After you upgrade
your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply
the standard upgrade process.
Higher Level Logical Link Limits
The numbers of logical links in the higher levels of the PNNI hierarchy is limited to 30 per level when
the complex node configuration is turned on. The limit is essential to reduce the processing time involved
in finding the bypasses between the logical links. Each time a significant change occurs in bandwidth in
one of the links within the peer group, the bypass calculation is triggered and the bypasses are usually
found from one logical link to another.
If there are n logical links, the calculation involves finding n*n bypasses.
If the number of logical links n is large, a lot of processing time is used to calculate the bypasses. Limit
the number of logical links per level to 30. To control the number, configure the appropriate number of
aggregation tokens for the outside links for that peer group.
AXSM-32-T1E1-E Notes
The following notes apply:
•
Inverse multiplexing over ATM (IMA) version fall-back is part of IMA group operation. If a group
is configured with Version 1.1 and it is connected to a far end group which is configured with
Version 1.0, this group falls back to Version 1.0.
•
The IMA link Loss of IMA Frame (LIF) and Link Out of Delay Synchronization (LODS) defect
integration times are configurable.
•
ATM layer configuration for line and IMA ports takes an additional parameter: Alarm Indication
Signal (AIS) enable. It is enabled by default.
•
In T1 mode, payload scrambling is disabled by default and in E1 mode it is enabled by default on
all lines and IMA groups.
•
Only 10 switched virtual circuit (SVC) calls per second are guaranteed.
•
Facilities Data Link (FDL) support for loopback code detection is not supported.
•
Far End Line Performance counters are supported only for E1. They are not supported for the
T1 interface.
•
Hidden Markov Method (HMM) support is not available for the IMA and the Framer devices. When
a switchover occurs, it can take up to 3.5 seconds for the IMA groups to recover. Data is lost until
the groups recover.
•
IMA Autorestart (persistent RX IMA ID) feature is supported.
•
The IMA group cannot have links from upper and lower bays configured together.
•
Independent Transmit Clock (ITC) clocking mode on IMA is not supported.
•
1-way transmission delay of more than 500 milliseconds (ms) on the T1/E1 IMA links is not supported.
•
There is 5 ms fluctuation on IMA delay tolerance.
•
While the IMA group accumulated delay is being removed using the clrimadelay command, the
following applies:
– Any changes to this IMA group configuration are temporarily blocked.

16
Part Number OL-8892-01 Revision B0, October 23, 2006
Limitations, Restrictions, and Notes for 5.3.00
– Any changes in the FE IMA links in this group can cause the NE IMA group to restart.
•
The Virtual Circuit (VC) and COSB thresholds are updated when the links are added/deleted from
the IMA groups.
•
The thresholds for the connections added when there are N links in the group can differ from
connections added when there are (N+1) links in the IMA group.
•
Bit error rate testing (BERT) is only supported on T1 interfaces. BERT is not supported on
E1 interfaces.
•
The port number in the pnport (shelf.slot:subslot.port:subport) could be a random number. Do not
interpret this number as line or IMA group number. Refer to CSCdy08500.
•
Private Network-to-Network Interface (PNNI) requires:
– Sustainable cell rate (SCR) = 453 cells per second and
– Peak cell rate (PCR) = 969 cells per second for the control connection
•
Service-Specific Connection-Oriented Protocol (SSCOP) requires an SCR = 126 cells per second
and PCR = 2000 cells per second.
AXSM-E Operation, Administration, and Maintenance Cells
The following notes apply to AXSM-E operation, administration, and maintenance (OAM) cells:
•
Any connection can receive E2E/OAM loopback cells up to the line rate (as long as the policing
policy permits).
•
If the connection is not in the loopback mode and is operating in the normal mode, then the AXSM-E
card can receive up to 1,500 segment OAM loopback cells per second. Any excessive segment OAM
loopback cells are dropped. This limitation applies for all the connections on a card.
For example, if only one connection exists, that connection can receive 1,500 segment OAM
loopback cells per second. If 2,000 connections exist on an AXSM-E card, and one segment OAM
loopback cell per second is being channeled through on each connection, then there can only be up
to 1,500 connections to receive loopback cells at any given second. The additional 500 connections
are not received for that second.
•
The limitation is 1,500 segment OAM loopback cells per card and not per connection. The 1,500 cps
assumes an even flow rate.
Command Line Interface Access Levels
The following notes pertain to configuring command access levels:
•
Not all command line interface (CLI) commands are changeable, and a command cannot be changed
to CISCO_GP group access level.
•
Only the switch software is allowed to generate the binary file. This binary file has an authentication
signature which has to be validated before the binary file can be used. Any manual changes to the
file make the file void.
•
If the binary file becomes corrupted, then the command access levels revert back to the default
values during the card bring-up. To recover, repeat the installation process or retain a copy of the
binary file and execute a cnfcli accesslevel install command on that service module.
•
Currently, command names are verified, but an invalid command name might be parsed and added
to the binary file. However, this invalid name is ignored later.

Part Number OL-8892-01 Revision B0, October 23, 2006
17
Limitations, Restrictions, and Notes for 5.3.00
•
If replication to standby failed, the installation process failed.
•
The cnfcli accesslevel default command restores all command access levels to default for the
service module that this command is executed on. This command does not remove the binary file,
and this change is not persistent. If the command is executed on the active card of a redundancy pair,
the standby card is not affected. When the card is reset and the binary file exists, it configures from
the binary file when it is brought up.
Disk Space Maintenance
Because the firmware does not audit the disk space usage nor remove unused files, the disk space in C:
and E: drives must be manually monitored.
Manually delete any unused saved configuration files, core files and firmware files, and the configuration
files of the MGX-RPM-PR-512 and MGX-RPM-XF-512 cards to avoid a shortage of disk space required
to store event logs: configuration upload files in the C: drive and the configuration of
MGX-RPM-PR-512 and MGX-RPM-XF-512 cards in the E: drive.
The following steps are recommended to remove files on the system from the active controller card:
Step 1
Change to the directory that needs grooming.
CLI cc <directory_name>
Step 2
List the directory to identify old files that can be removed and available disk space.
CLI ll
Step 3
Remove any old files (you may also use wild cards in the filename).
CLI rm <complete_filename>
Step 4
List the directory to see if the file was removed and disk space is available.
CLI ll
Saving Configurations
The system keeps only the two most recent copies of the saved system configuration under the C:/CNF
directory. You can use FTP to transfer all of the saved configurations under C:/CNF to their local server
for future reference. All files under C:/CNF are not replicated over to the standby controller card under
any circumstances.
Using the clrsmcnf Command
These notes pertain to the clrsmcnf command:
•
We do not recommend executing clrsmcnf on more than one card at a time
•
For the clear service module configuration feature, if there is a controller card switchover before the
clear service module configuration operation is complete, the clrsmcnf command must be re-issued
to ensure that the configuration is completely cleared to avoid an incomplete cleanup.
Release Notes for Cisco MGX 8880 Software Release 5.3.00
18
Part Number OL-8892-01 Revision B0, October 23, 2006
Limitations, Restrictions, and Notes for 5.3.00
•
For the clear service module configuration feature, using the clrsmcnf command might result in
discrepancy in the PNNI configuration. For example, some connections might be in the mismatch
state.
•
If the clrsmcnf command is given with the <all> option to clear the software version for the slot as
well, then the card enters the boot/empty state after the operation is complete.
•
If the clrsmcnf command is given with the <all> option, for cell bus service module, the card enters
boot/empty state. For a broadband service module (for example, AXSM or MPSM-155-T3E3), the
card enters fail/active state.
•
While using the clrsmcnf command, the card in the specified slot is not usable until the operation
is successfully completed.
AXSM Card Automatic Protection Switching Limitations
These notes pertain to the Automatic Protection Switching (APS) feature:
•
For AXSM APS, the back card of the active card must be present for APS to function.
•
AXSM cards need the back card of the active front card for the APS to work. This implies that
AXSM cards do not support the cross backcard removal—the upper backcard of one AXSM and
lower backcard of another AXSM.
•
If you remove the upper back card of the active front AXSM, it triggers switching active card. The
APS is OK. However, if the lower back card of the current active AXSM is removed at this time, it
does not trigger switching the active card because the standby card is missing one of the back cards.
The lower backcard APS does not work because the back card of the active front card is missing.
•
Port LED lights on AXSM-E front cards indicate the receive status of the physical line connected to
it only when the card is in active state. For standby AXSM-E cards, the LEDs always remain green
when the lines are in loss of signal (LOS) irrespective of which lines are active (refer to anomaly
CSCdv68576).
Path and Connection Trace Features
These notes pertain to the path and connection trace features:
•
Path trace is not supported on the control port.
•
Path trace does not have the accurate information when there is a crankback on the connect path.
•
Path and connection trace support point to point connections.
•
Path and connection trace support MPG (multiple peer group) and SPG (single-peer group).
Priority Routing Feature
These notes pertain to the priority routing feature:
Prioritized reroute of soft permanent virtual connection (SPVCs) is not guaranteed if the SPVCs
originate on a signaling port. SPVCs might get routed out of order. In-order routing of SPVCs is
guaranteed on non-signaling ports.
•
RPM does not support configuration of routing priority. All RPM mastered SPVCs are assigned a
routing priority of 8 by the PXM.
Release Notes for Cisco MGX 8880 Software Release 5.3.00
Part Number OL-8892-01 Revision B0, October 23, 2006
19
Limitations, Restrictions, and Notes for 5.3.00
•
Changing the routing priority for DAX connections does not change the priority of the associated
SVCs. The SPVCs are not derouted and rerouted if just the endpoint parameters are changed, and
routing priority is an endpoint parameter. Also, because DAX connections are never derouted even
if the user-network interface (UNI) port stops responding and the rrtcon command is not supported
for DAX connections, the routing priority change is never reflected. The only way for the routing
priority change to be reflected is to execute the dncon and upcon commands. Because DAX
connections are never derouted, the effect of this limitation is voided.
•
Priority routing operates in a best effort manner for the following reasons:
– Two in-order releases can still arrive out of order at the master node if they take two different
paths.
– Under congestion scenarios releases can be expected to be transmitted out-of-order. This is
because releases of other calls must not be held up if you are not able to send releases on one
of the interfaces because it is congested. The calls that were not released could be higher priority
calls.
– Lower priority SPVCs can be routed ahead of higher priority SPVCs. This can happen if you
have repeatedly failed to route higher priority SPVCs. To prevent starvation of lower priority
SPVCs, the software starts to route lower priority SPVCs. The software eventually addresses
the higher priority SPVCs later.
Soft Permanent Virtual Connection Interoperability
These notes pertain to SPVC interoperability:
•
Network-to-Network Interface (NNI) SPVC Addendum Version 1.0 is not supported.
•
CC (Continuity Check) is not available at the slave end of a single-end SPVC.
•
Reporting AIS detection to Cisco Wide Area Network Manager (CWM) is not available at the slave
end of a single-end SPVC.
•
The slave end of a single-end SPVC is not visible to CWM.
•
If single-end SPVCs originated from MGX switches, they can only be configured through CLI and
not from CWM in the current release.
•
Single-end provisioning is not supported for DAX connections.
•
SPVC statistics are not available for the slave endpoint of a single-end SPVC because this endpoint
is nonpersistent.
•
When the persistent slave endpoint of an existing SPVC connection is deleted and the master
endpoint is allowed to remain, the connection might become established as a single-end SPVC
connection. In this case, CWM shows the connection as Incomplete.
•
Override of SVC connections on a virtual path identifier (VPI) due to an incoming SPVP request for
that VPI is not supported. The following override options are supported only:
– spvcoverridesvc
– spvcoverridesvp
– spvpoverridesvp

Part Number OL-8892-01 Revision B0, October 23, 2006
Known MGX 8880 Media Gateway Anomalies
Manual Clocking
When resetcd is invoked, the primary and secondary (if configured) clock sources are recommitted.
However, the clock to which the node is latched is not requalified. Only the backup clock is qualified if
present. Recommitted means that the primary and secondary are requalified, and the node temporarily
latches onto the internal oscillator. After the clock is requalified, the node locks onto the primary clock
source once again.
Enabling Priority Bumping
When you enable priority bumping on the node, you cannot change the booking factor for AXSM
signaling ports. You can change the booking factor for non-signaling ports.
Other Limitations and Restrictions
Other limitations and restrictions are as follows:
•
When configuring virtual interfaces (for example, VUNI, VNNI, EVUNI, EVNNI), the physical
interface must be of all one ATM header type, either UNI or NNI. The signaling that is applied to a
virtual port is independent of the actual virtual port ATM header. The only limit is that the VPI value
must be within the UNI ATM header limitations.
•
If command clrchancnt is executed while a dspchancnt command is currently active, the displayed
data is incorrect. To display correct data, restart the dspchancnt after the previous one is complete.
•
The clrsmcnf command does not work:
– For redundant service modules.
– If an upgrade is in progress.
•
If RPM-XF is configured as a Label Switch Controller (LSC), execution of clrsmcnf command on
those LSC slots is rejected.
•
Configuration information is not synchronized between processor switch modules (PXMs) during
upgrades. If any changes are made to the configuration during upgrades, the standby PXM must be
rebooted. The standby PXM must be rebooted when it is in a stable state.
Clearing the Configuration on Redundant PXM45 Card
These notes apply to redundant cards.
•
Due to checks to prevent an inserted card from affecting the system, an additional step might be
required when inserting two non native PXM45 cards in a shelf. Insert the first PXM45, use the
clrallcnf command, and allow this to become active before inserting the second PXM45.
•
After a clrallcnf, explicitly clean up stale SCT files (see anomaly CSCdw80282).

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability
in a Cisco product, contact PSIRT:
•
For Emergencies only — [email protected]
An emergency is either a condition in which a system is under active attack or a condition for which
a severe and urgent security vulnerability should be reported. All other conditions are considered
nonemergencies.
•
For Nonemergencies — [email protected]
In an emergency, you can also reach PSIRT by telephone:
Tip
•
1 877 228-7302
•
1 408 525-6532
Use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive
information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP
versions 2.x through 9.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence
with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page
at this URL:
http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html
The link on this page has the current PGP key ID in use.
If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers
before sending any sensitive material to find other means of encrypting the data.

Obtaining Technical Assistance
Cisco Technical Support & Documentation Website
The Cisco Technical Support & Documentation website provides online documents and tools for
troubleshooting and resolving technical issues with Cisco products and technologies. The website is
available 24 hours a day, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user
ID and password. If you have a valid service contract but do not have a user ID or password, you can
register at this URL:
http://tools.cisco.com/RPF/register/register.do
Note
Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting
a web or phone request for service. You can access the CPI tool from the Cisco Technical Support &
Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose
Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco
Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by
product ID or model name; by tree view; or for certain products, by copying and pasting show command
output. Search results show an illustration of your product with the serial number label location
highlighted. Locate the serial number label on your product and record the information before placing a
service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447
For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
